As I-285 forms a complete circle around Atlanta (much as I-465 does around Indianapolis), I don't see how he could get lost on it, as he'd eventually end up back at the exit he was supposed to take. IIRC, I-75 runs right past where Atlanta Fulton County Stadium used to be, and Turner Field currently is, as one can see it from the highway.

Rest in peace, Mr. Perez.

When I was in college, coming back to Central Illinois from a road trip that took us east of Indianapolis, we got lost on I-465 because on the way to our destination through Indy we took south 465 so, natch, on the way back, we assumed we needed to take north 465 but alas, we somehow ended up on I-65 toward Chicago.
